E School Today: The Changing State of Matter
Learn about the changing states of matter.
PBS
Pbs: Nova: Absolute Zero: States of Matter
This interactive allows you to explore the effect that temperature and pressure have on the changes in the states of matter. You can test these variables on carbon dioxide, hydrogen and water.
American Chemical Society
Middle School Chemistry: Changing State: Melting
Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.
American Chemical Society
Middle School Chemistry: Changing State: Evaporation
Students build a model of a water molecule and design an experiment to see if adding energy affects the rate of evaporation.

E School Today: What Is Matter
Learn about matter, its three states, changes of state, how matter behaves, and physical and chemical changes in matter.
Children's Museum
The Children's Museum of Indianapolis: Color Changing Milk
Learners observe a molecular dance of bursting colors through exploring states of matter and learning that materials can be characterize by how they respond to water.

Middle School Chemistry: Changing State Freezing
Discover how freezing works, when the change of state moves from liquid to solid.
Center of Science and Industry
Cosi Columbus: Can You Stand the Pressure
Science experiment that demonstrates the four states or phases of matter: solid, liquid, gas, and plasma. Includes full list of materials, procedures, and scientific explanation of how you change water from a liquid state to a gaseous...
